I for one have some issues when someone tries to go and do a test and quotes openly that the detection rate has been at the expense of false positive.

In any good antivirus, they should have very few false positive as much as possible. Customers whom maintain computers rely on AV programs to tell them what is bad. if AV programs can sacrifice false positive for better detection rate, we don't need an antivirus, just mark all files as bad and we might just score 100% detection rate.

Remember that false positives can be destructive.....some of you may remember about a recent incident where Symantec flagged a critical file for Chinese based Windows. It was a fully legitimate file and it was not infected and the consequences was that, by deleting/quarantining that file, thousands of Chinese Language Windows computers could not start up because it was a critical file needed by Windows to startup. You don't want this happening more often.....
